[B-chronic lymphocytic leukemia/prolymphocytic leukemia (CLL/PL)--a case report].
A 48-year-old male was admitted to our hospital on April 20, 1989 because of general fatigue and abdominal fullness. Physical examination showed hepatomegaly, massive splenomegaly, and systemic lymphadenopathy. Hematological findings revealed WBC 73,000/microliters, RBC 289 x 10(4)/microliters, Hb 8.0g/dl, and platelet 9.1 x 10(4)/microliters. WBC differential count demonstrated a mixture of 63% matured small lymphocytes and 32% prolymphocytoid cells. Bone marrow aspiration was unsuccessful with a dry tap. Surface marker analysis of peripheral blood lymphoid cells disclosed that they were positive for anti-HLA-DR, CD 5, CD 19, CD 20, CD 21, CD 25, Sm-IgM, Sm-IgD, and Sm-K. He was diagnosed as B-CLL/PL, and treated with VEPA with partial remission. CLL/PL which was advocated by Melo in 1986 is regarded as a distinct clinical entity intermediate between CLL and PLL in clinical and laboratory features. Our case is interesting with regard to good response to combination chemotherapy, though most cases of CLL/PL have a resistance to standard chemotherapy.
